One of the biggest trends in the switch and relay markets is the call for more options to help designers select the best switching device for their application. Other big asks are for longer life, ...

An electrical relay is a type of heavy-duty, remote-control switch able to handle high-current accessories, yet capable of being actuated by substantially less current. Relays install between the ...

We show you how to wire in an electric fan relay kit with a thermostatic switch. If you've got an electric cooling fan on your classic car or hot rod and you want to know how to wire it with a relay, ...

Real switches and relays exhibit a finite resistance called “contact resistance,” which increases over time with the number of actuations. Furthermore, as a switch or relay changes state, the contacts ...

With switching a capacity to 20A, A4 Series automotive relays offer contact arrangement options of SPST N.O. and SPDT and are available in a dual relay package. Coil-voltage options include 3, 5, 6, 9 ...

Standex Electronics has created a reed relay that measures 7.95 x 4.67 x 3.6mm and can switch 100V, 200mA, 3W or 8GHz. 8GHz is the -3dB frequency, at which the switch offers -5dB isolation when open. ...

Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...
